Способ получения альфа-олефиновых высокомолекулярных полимеров в растворе, выбранных из группы, состоящей из гомополимеров этилена и сополимеров этилена и высших альфа-олефинов С3-C12. Способ включает подачу мономера, выбранного из группы, состоящей из этилена и смеси этилена и по меньшей мере одного высшего альфа-олефина C3-C12, координационного катализатора и инертного углеводородного растворителя в реактор, полимеризацию указанного мономера при температуре в интервале 105-320°С, и выделение полученного таким образом полимера. Координационный катализатор образуется из MgR 1 2 и AlR 2 3 , в которых каждый R1 и R2 является одинаковым или различным и представляет собой алкильную группу, имеющую 1-10 атомов углерода, реакционноспособного хлоридного компонента, соединения титана, выбранного из четыреххлористого титана, четырехбромистого титана, и соединения формулы Ti(OR)x, в которой х = 0-4 и R является алкильной группой, имеющей 1-10 атомов углерода и спирта.The method of obtaining alpha-olefin high molecular weight polymers in solution, selected from the group consisting of homopolymers of ethylene and copolymers of ethylene and higher alpha-olefins With 3 -C 12 . The method includes feeding a monomer selected from the group consisting of ethylene and a mixture of ethylene and at least one higher alpha-olefin C 3 -C 12 , a coordination catalyst and an inert hydrocarbon solvent to the reactor, polymerizing the specified monomer at a temperature in the range 105-320 ° C, and the selection of the thus obtained polymer. Coordination catalyst is formed from MgR one 2 and AlR 2 3 in which each R 1 and R 2 is the same or different and represents an alkyl group having 1-10 carbon atoms, a reactive chloride component, a titanium compound selected from titanium tetrachloride, titanium tetrabromide, and compounds of the formula Ti (OR) x , in which x = 0-4 and R is an alkyl group having 1-10 carbon atoms and alcohol.
